Why This Matters: As the authors of the study contend, “Perennial vegetables are a neglected and underutilized class of crops with potential to address 21st-century challenges.” These vegetables contain immense nutritional benefits, as well as benefits to the environment. The study, in Gewin’s words, showed that by “increasing perennial vegetable acreage to 26 million hectares (from roughly 3.3 million hectares today) by 2050 [we] could store an additional 280.6 million metric tons of CO2 equivalent per year.” Plus, growing these vegetables can help address the nutrient deficiencies that affect more than 2 billion people. So please eat your perennial veggies — its good for all of us!
A Life-Giving Vegetable
Many followers of permaculture have lauded the benefits of perennial vegetables. This study echoes these thoughts. The lead author of the study, Eric Toensmeier, told Civil Eats, “There are so many cases where a plant on this list will have more than twice the amount of key nutrients of traditional vegetables you can buy at the store.” Some of the plants Toensmeier is particularly interested in include moringa and Nopales cactus.
But the benefits do not stop there. The plant also offers numerous benefits to the environment. The potential storing of carbon dioxide is, as Gewin noted, “roughly the same as cutting meat from American diets or eliminating the emissions of 60 million cars.” In addition, there are short-term benefits that cultivating these plants can confer upon farmers. As Stacy Reader, a research associate at the agricultural non-profit ECHO told Civil Eats, by growing perennial vegetables, “farmers see the benefits of having trees on farms—chiefly, the soil stays in place.”
However, this is not to claim that perennial vegetables are a panacea to world hunger and climate change. Reader made the essential point to Civil Eats that, “Adoption [of a new species] goes over best when it’s needed by the community and promoted by farmers in the region.” The planting of different and diverse perennials must be a community- led and engaged effort.
There are further questions the study raises which must be answered. In the words of Courtney Leisner, Assistant Professor of Biological Sciences as Auburn University, this paper should be treated as a “to-do” list. Some of the questions that must be answered include, “ Where can these crops be grown? What percentage of the nutrients are bioavailable? How climate hardy are these crops?” But to Leisner the most important question of all is “Where should we focus our resources next.”
This year’s smaller gatherings due to the pandemic provide another opportunity to re-set holiday traditions for the better, writes Priya Krishna for the New York Times. She explains that sustainability is a part of Native American culture and as well as the heritage of many ethnic Americans. Yet, the way we usually prepare Thanksgiving’s big […]
This week, McDonald’s announced that it was launching the McPlant burger, a completely vegan burger created by the fast-food chain and Beyond Meat. The release is a part of the company’s effort to reduce its carbon footprint, 29% of which can be attributed to the sourcing of beef.
The COVID-19 pandemic is “ratchet[ing] up the pressure” to automate harvesting processes, Civil Eats reported. Alongside the rising cost of labor and the increasingly dangerous conditions caused by wildfires, more and more farmers are considering this move to automate their harvests with robots replacing up to half the farmworkers currently needed.
